Powering On the Controller

AX1500 Quick Start

Powering On the Controller

Important reminder: There is no On-Off switch on the controller. You must insert a switch on the controller’s power terminal as described in section“Connecting to the Batteries and Motors” on page 17.

To power the controller, center the joystick and trims on the R/C transmitter. In Analog mode, center the command potentiomenter or joystick.Then turn on the switch that you have placed on the on the Power Control input.

A Power LED located next to the 15-pin connector will lit to indicate that the controller is

ON.

The status LED will start flashing a pattern to indicate the mode in which the controller is in:

RC Mode

RS232 Mode No Watchdog

RS232 Mode with Watchdog

Analog Mode

FIGURE 5. Status LED Flashing pattern during normal operation

Default Controller Configuration

Version 1.9b of the AX1500 software is configured with the factory defaults shown in the table below. Although Roboteq strives to keep the same parameters and values from one version to the next, changes may occur from one revision to the next. Make sure that you have the matching manual and software versions. These may be retrieved from the Roboteq web site.

TABLE 1. AX1500 Default Settings

Parameter	Default Values		Letter

Input Command mode:	(0)	= R/C Radio mode	I

Motor Control mode	(0)	= Separate A, B, speed control, open loop	C

Amp limit	(5)	= 26.25A	A

Acceleration	(2)	= medium-slow	S

Input switch function	(3)	= no action	U

Joystick Deadband	(2)	= 16%	d

Exponentiation on channel 1	(0)	= Linear (no exponentiation)	E

Exponentiation on channel 2	(0)	= Linear (no exponentiation)	F

Left / Right Adjust	(7)	= no adjustment	L

Any one of the parameters listed in Table 1, and others not listed, can easily be changed either using the PC with the Roboteq Configuration Utility. See “Using the Roborun Config- uration Utility” on page 161.
